srnineme or VEHIC ES.

To all whom it may concern:

Be it known that LAn'ri-ron J OHN ADAMS a subject of the King of Great Britain, and resident of The Cottage, Heywood, near VVestbury, in the county of Wilts, England, have invented a certain new and useful Im movement in the springing of Vehicles, of which the following is a specification.

This invention relates to improvements in the springing of road and other vehicles of the kind wherein the vehicle frame is attached to the axle by means of bell-crank levers arranged in pairs, the members of each pair being pivotally connected together, andwherein a spring is provided to resist relative movement of these levers.

about their pivotal connection, such as is described in the specification of an appli cation for Letters Patent of even date here h... i

According to this invention, in order to maintain the thrust plates for the spring in constant alinement, the thrust plate attached to one of thelevers is pivotally connected "thereto by eyebolts swinging about an axis which passes through the spring transversely I to the axis of the latter. The pivots on which the said eyebolts turn are constructed similarly to the knife edge bearings forthc beams of weighing scales or balances, so

'that there is a rolling instead of a rotary contact between these parts whereby efiicient working of the springing construction will not be prevented byrust and the necessity for lubrication is avoided. The eyebolt pivots are carried'by a yoke which is formed as an extension of the cap holding one of the levers on the axle casing of the vehicle to which the improved springing is fitted. v

Preferably, the bushes at the extremities of the levers, through which the pins attaching the levers to the vehicle. frame are passed, are made of a barrel-shape so that they can'rock in the eyes at the ends of the levers and are therefore self-alining, thus preventing the transmission of any lateral bending stress to these levers.

The-improved method of springing is applicable to both the front and the rear axle springs of vehicles, and the main lever, i. c. the one attached to the axle. casing, may extend forwardly or 'backwardly as required by the construction of the vehicle frame. In

t the case of either a front axle or a rear- Specification of Letters Patent.

axle spring the main lever on one side may be fixed to the axle casing, e. g. by a key,

so as to form a torque rod for the axle, or v the levers on both sides may be free if a' the said invention may be conveniently and advantageously carried into practice.

In this drawing:

Figure 1 is a side view, and 7 Fig. 2' an underside view of an axle springing constructed acccording to this invention;

Fi 3 is an end view thereof, looking fromthe leftof Fig. 1.

.. 4: and 5 are detail views, on an enla r ed scale, hereinafter-described.

. ig. '6 is a detail view illustrating a modiby varying the position of the plate f which iscarried on the said boss 2'.

The. lever a is provided with a cap j by which it issecured to the axle casing, and this cap has a yoke formed integrally therewith. As shown in Fig. 4, each arm of this yoke supports a pivot pin Z having" Eyebolts i n, a bearing against this knife edge m carry a knife edge m formed thereon.

a second thrust plate 0,. and a spring 7) washers a of anon-corrodible material are provided at the sides of the eyebolts n to prevent looking or setting of these parts by rust. w

Relative movement between the levers a, b about the pivot pin'd when a load is applied to the eye'(:, a, is resisted by this spring as will be readily understood, and when any such movement takes place the pivotal mounting of the eyebolts g and n, n preserves the alinement of the thrust plates f and 0.

In Fig. 1, the cap 7' is shown fitted with is held between these thrust plates. Thin end, a single pivotal joint connecting said levers at their adjacent ends one toa feather or key 8 to secure the lever a to the axle casing when this lever is used as a torque rod.

The eyesc, 0 are fittedwith barrel-shaped bushes g, as shown in section in Fig. 5, held in the eyes by set screws 1", this arrangement permitting these bushes to adjust themselves into alinement with the pins by which the levers a, b are attached to the vehicle frame. 7

An alternative form of the lever b is illustrated by Fig. 6, in which the arm 6, corresponding to the arm e of Fig. 1 is formed with a ball t-atthe end thereof, and the corresponding thrust plate f is formed with a socket a receiving this ball.

What 'I claim is 1. A springing for vehicles comprising in combination two levers arranged end to end, a single pivotal joint connecting the said levers at their adjacent ends one to the other, means for connecting the said levers to a vehicle frame at their remote ends, means carried by one only of the said levers for attaching this lever to an axle casing, said axle casing lying in a vertical plane parallel to the plane in which is situated said single pivotal joint, an arm projecting from one of said levers, a yoke projecting from the other of said levers, and a spring interposed between said arm and said yoke projecting respectively from the said levers.

2. A springing for vehicles comprising in combination two levers arranged end to end, a single pivotal joint connecting the said levers at their adjacent ends one to the other, means for connecting the remote ends 7 of the said levers to a vehicleframe, means carried by one only of the said levers for attaching this lever to an axle casing, an

arm and a yoke projectin respectively from thesaid levers, thrust p lates' pivotally connected to the said arm and yoke respectively, and a spring between the said thrust plates. i I V 3. A springing for vehicles comprising in combination two levers arranged end Itlo t e the other, means for "connecting the said levers'to a vehicle frame at their remote ends, means carried by one only. of the said.

levers for attaching this lever to an axle casing, said axle casing lying in a. vertical plane parallel to the plane in which is situated said single pivotal joint, an arm projecting from one of the levers, an eyebolt pivotally connected thereto, a nut adjust able along the eyebolt,'a thrust plate supported by the said nut, a second thrust plate pivotally connected to the other of said levers, and a spring between the said thrust plates.

4. A springing for vehicles comprising in combination two levers arranged end to end, a single pivotal joint connecting the said levers at their adjacent ends one to'the other, means for connecting the said'levers to a vehicle frame at their remote ends, a

detachable cap securing one of the said other, meansfor connecting the said levers,

to a'vehicle frame at their remote ends, a detachable cap seourlng one of the said levers to an axle casing, ayoke extending a from the said cap, pivot pins'supported by the arms of the yoke, eyebolts bearing against said pins,'a thrust plate carriedby the other one of the said levers, and a spring arranged between the said thrust plates.
